Sea Ray 250 Select EX 2006 vs Sea Ray 290 Sundeck 2008: Same Brand, Different Boat

The Sea Ray 250 Select EX 2006 vs Sea Ray 290 Sundeck 2008 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department - Sea Ray 250 Select EX 2006 at 26,0 ft versus Sea Ray 290 Sundeck 2008 at 29,0 ft. Weight tells a clearer story for trailering families: the Sea Ray 290 Sundeck 2008 tips the scales at 6 044 lbs - 994 lbs less than the Sea Ray 250 Select EX 2006 at 5 050 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling - 425 hp for the Sea Ray 250 Select EX 2006 and 425 hp for the Sea Ray 290 Sundeck 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Sea Ray 290 Sundeck 2008 carries 93 gallons versus 75 gallons in the Sea Ray 250 Select EX 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Sea Ray 290 Sundeck 2008 at 29,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 250 Select EX 2006 at 26,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.

Sea Ray 250 Select EX 2006 vs Sea Ray 290 Sundeck 2008 - Common Questions

Which is the larger boat - the Sea Ray 250 Select EX 2006 or the Sea Ray 290 Sundeck 2008?
The Sea Ray 290 Sundeck 2008 is the longer of the two at 29,0 feet overall. The Sea Ray 250 Select EX 2006 comes in at 26,0 feet, making it roughly 3,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Sea Ray 250 Select EX 2006 or the Sea Ray 290 Sundeck 2008?
For trailering, the Sea Ray 250 Select EX 2006 has the edge at 5 050 lbs dry weight versus 6 044 lbs for the Sea Ray 290 Sundeck 2008. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Sea Ray 250 Select EX 2006 is Coast Guard rated for 8 passengers, while the Sea Ray 290 Sundeck 2008 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing - on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Sea Ray 290 Sundeck 2008 measures 109" wide, compared to 102" for the Sea Ray 250 Select EX 2006. The US standard-width towing limit is 8’6" (102") in most states - anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank - the Sea Ray 250 Select EX 2006 or the Sea Ray 290 Sundeck 2008?
The Sea Ray 290 Sundeck 2008 has the bigger tank at 93 gallons, versus 75 gallons on the Sea Ray 250 Select EX 2006. That 18-gallon difference translates to roughly 54–90 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes - both the Sea Ray 250 Select EX 2006 and the Sea Ray 290 Sundeck 2008 are built by Sea Ray. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
